The RV Sani-Con System provides an alternative method to empty the tanks on Road Trek RVs.

The Road Trek is a very popular RV.  According to the manufacturer, all of the comforts of a big rig are presented in a much smaller package.  At the request of several Road Trek owners, we will offer an alternate method to the tank emptying system furnished as standard. Based on the patented RV Sani-Con System, you can easily reach into the adjacent storage compartment and remove a 1” diameter x 21 foot long discharge hose and nozzle. Remove the 1” drip cap on the discharge nozzle and place the nozzle into the sewer. Open the valve of the tank you would like to empty and flip a switch, empty the tanks, and simply store the hose away. If your vehicle has a compartment next to the sewer pipe compartment, you should be able to install the system as below. We make no warranty that you system is as shown, however. This is offered as a suggestion only. You may want to consult your technician to determine the suitability of this installation.

 The installation of the RV Sani-Con Model RT6003 is very simple and you do not abort or alter the function of the factory installed hose carrier system. You will need a saber saw with a blade to cut plastic pipe, a Phillips screwdriver, a straight blade screwdriver, a marking pencil that will show on black pipe, a 1 ¼” hole saw, ½” bit, and electric drill. You will also need a drop light, or a large flashlight.

General Installation Information

Generally, to install the RV Sani-Con Model RT6003, you will prepare the 4” carrier pipe to receive a pump and motor that is connected to the existing 3” flexible sewer hose. Then the discharge of the pump is connected to the             1” x 21foot  hose furnished  with the RV Sani-Con System. A hole is made in the compartment wall to allow the discharge hose to be stored in the adjacent compartment.  The power circuit is hooked up to the vehicle battery and the basic installation is complete.

Specific Installation Information

First, remove the pin on the hinged door and  lower the 4” black carrier pipe. Remove the heavy web loop that holds the pipe off the ground when you remove the blue hose. Remove the black plastic adapter on the end of the blue hose, and stick the hose back down into the pipe. Next we will prepare the slot in the 4” pipe to receive the pump and pump discharge barb.  With a felt tip pin marker that will shine or mark on the 4” black pipe, make a mark at the 1 o’clock position on the pipe wall, below the steel pin that is fastened to the pipe. (this is the pin that holds the pipe in place on the hinged door).  Measure down 1 ¼” to the 3 o’clock position on the end of the pipe. Draw a line on the pipe that is 7” long from the end of the pipe on each mark. This line should be straight and parallel to the pipe center. At the end of the lines, connect the ends so you will know when to stop sawing.  You will not need to saw the short 1 ¼” line marked, you can just lift it up and break it off.  Before starting to saw the opening, push the blue hose down into the 4” pipe to prevent the saw from cutting into the hose. You can block the hose with a screwdriver at the view port cut into the 4” pipe.  The cutting maneuver requires a little caution to get the saw set to make the parallel cuts. Stop the saw at the end of the 7” line. Then simply lift the 11/4” piece that is 7” long up and break it off. The pipe is soft and the piece will easily be removed.  Now the slot will allow the pump to slide into the 4” pipe.

Before you install the pump and motor, pull the blue sewer hose from the pipe, place the 3” clamp that is included with the pump and motor over the end of the blue hose.  Slip the blue hose over the gasket on the inlet of the pump. The gasket is an exclusive of RV Sani-Con and makes for a proper non-leaking connection. Tighten the clamp snugly but do not over tighten and bite a hole into the blue hose.  Slide the motor into the pipe and align the discharge of the pump into the slot until it bottoms out at the end of the slot. Store the two wires from the pump motor in the slot for the time being.

At this time, lift the pipe up and return the web pipe hanger back to the vehicle frame. Place the pin into the hinged door and install the locking pin.  The discharge  of the pump should be pointing toward the wall of the compartment next to the pump and motor.  With the marker pen, make a mark on the wall of the outside of the compartment where the discharge barb points to the wall. If the wall of the compartment is fiberglass or plastic, you will be able to light the wall outside and see the mark on the inside of the compartment.  Make a mark on the inside wall to drill the connection hole with the hole saw. If you are unable to see the mark, accurately determine the center of the hole barb and make a mark on the inside. Drill a small test hole to check the accuracy of the connection hole.  The hole saw should be slightly larger than the diameter of the rubber cuff on the end of the discharge hose. If the position of the hole is correct, using the hole saw,  drill the connecting hole.  Avoid drilling into the pump discharge opening when going through the wall. Make sure the hole is smooth and free of jagged edges that might cut into the wall of the discharge hose. You may want to wrap a layer of duct tape around the hose where the penetration is determined. Place a clamp around the hose discharge before pushing the hose onto the barb. This will be a good time to pull the red switch wire into the compartment, make a loop and back out to the pump. The loop will be cut and connected to the switch later.

The other end of the red wire will be pulled to the power source up into the engine compartment. The black wire can be pulled at the same time as the red wire. Red is positive and black is negative.

Your installation will be finished when the wiring is pulled and the switch installed. The switch bore is ½” diameter. You may find a spot that is more suitable than is shown in the picture, however the owner of the vehicle preferred this placement.

Wire tie the wires to prevent being pulled or cut. Put sealant around the connection hole to prevent water from entering the compartment.

Operation of the System

The functions of emptying the tanks are very simple. Remove the discharge hose and nozzle, remove the drip cap, and insert the nozzle into the sewer opening. Open the valve of the tank you want to empty and turn on the switch. When the motor runs faster, the motor sound changes. This sound change will indicate the tank is empty. Turn off the pump.  Pump volume is approximately 12 gallons per minute. When you are finished, replace the small drip cap and lay the hose in the storage compartment. You are ready to travel.

Note:  You may leave the gray valve open when you are connected to a park sewer pipe.  Just turn on the switch until the sound changes.

This article is written to cover the vehicle as shown in the photos. Some variations in conditions may appear from vehicle to vehicle. As other photos become available or if you would like to offer photos for the benefit of other applications, we will try to offer them on our web site. The RV Sani-Con System Model RT 6003 will fit most applications that have a 4” pipe. Other pumps will not.  If you would like to discuss this installation, please call 859 296 4604,          8-5 EST, Monday-Friday. Just ask for Road Trek applications.
